The strangest thing I can remember is when I was going to a class on the other side of the harbour bridge and when I arrived someone making some small talk said 'how did you get here did you come over the bridge'. I had only recently read somewhere that if you can say something seriously enough then people will believe anything. So on the spur of the moment I said casually 'No, I came under the bridge', they said 'under the bridge?' and I said "yeah, I came with my scuba diving gear and left my car and walked under the water to get here. I expected her to laugh but was astounded to see that she believed the story. Which is a bit of a worry.
